19 Dumb Things Celebrities Have Said on Twitter

After Penn State fired football coach Joe Paterno because he helped cover up a child rape case, Kutcher Tweeted: "How do you fire Jo Pa? #insult #noclass as a hawkeye fan I find it in poor taste." He may not have had all the information at the time.

Amanda Bynes has plenty of issues. But she thinks Drake is ugly?!? "@drake please don't think you're good looking!" she once wrote. "Ew!...I'll post ugly pics of @Drake every time I see one! Not hard ;)...Ugly far apart eyes."

Alec Baldwin has a temper problem. That was never more evident than when he went on a homophobic rant against The Daily Mail writer George Stark, Tweeting: "I'm gonna find you, George Stark, you toxic little queen, and I'm gonna fuck… you… up. I'd put my foot up your fucking ass, George Stark, but I'm sure you'd dig it too much."

Lohan removed the N-Word reference in this Tweet not long after she posted it (following a Kanye West concert). But nothing ever disappears from the Internet!

"If Everybody In The World Dropped Out Of School We Would Have A Much More Intelligent Society . . . Everybody Get Off Your Phones And Go Do What You Actually Wanna Do." We do agree with the second part of his statement.

Anthony Weiner DID dumb things on Twitter more than say them, but come on. We can't NOT include him here.
